[quote user="Romy the Cat"]Ok, let kill the subject of Oleg Rullit out of this thread. Rullit has very little to do with horn and consequentially with compression drivers. Sine this thread is about MF compression driver I think there is no reason to ...

[quote user="Romy the Cat"]Audiofilofine, I have no formed opinion about what Rulit does. I do not want to steer the subject of the thread to the wrong direction but can you share your view and your reasons why you feel that what Rulit does is a fant...

Leaving open the magnetic flux to the nucleus is smaller and therefore the tweeter sounds much slower . All the tweeter is in magnetic steel ( except in some parts ) but the magnetic force is concentrated on the core . Since I use a translator to try...

After several tests of listening and somehow I felt that the best solution is fully closed. The heat is part of the project and not to damage the diaphragm, also the hot air is compressed better than cold and thus distorts less. Even leaving the cont...

[quote user="vinylithicum"]Here are some of my observations regarding the Wolf von Langa RCA 1428 replica. I long time wondered where mr. von Langa gets his phase correction elements and the diaphragm for his RCA 1428 replica. It's obvious that a nic...

[quote user="Romy the Cat"]audiofilofine, you need to examine your room and your entire domestic environment in order to see where and how you might make your pair of bass horns. Also, if they will be 20Hz horn then are you planning to use next chela...

[quote user="Romy the Cat"]audiofilofine, you need to form a question in a format that would indicate you do the your do some homework. To bulb or even to design 20Hz horn is complex task and it usually made to the specifics of the given circumstance...

to reel from 7 volts or 700 volts is equal to the reel. should rather ask why or why 7 or 700 volts. should be asked how you intend to use the horn driver, you should ask graphs of frequency response and power handling. build a field coil driver is ...

I have not made any measurements on these drivers, I've just heard.
at 100 volts the sound is similar to the original Alnico magnet, at 130 volts instead of the original seems to be more shr...

Haralanov,I spoke with a guy who consulted me during my Electo-Vitavox project. He helped me with selection of core material, deliberated the core and calculated the right coil to keep the core mass optimally magnetized....

I agree that it is the diaphragm or the glue to soften with heat, I think maybe it's the hot air that the diaphragm has before changing qualcosa.possibile?

[quote user="Romy the Cat"]So, I guess you do not measure flux if are getting. You might measure sensitivity and we might presume what when perm magnets has the same sensitivity as electromagnets then the drivers have the same magnetic flux density. ...

yes romy but my english is badThe JBL 2420 alnico sweet sound with my trumpet tactrix not felt the need for a tweeter, but the high was a bit behind. with the field coil at 100 volts sounds almost equal all'alnico but increasing to 130 volts, so that...
